A few days ago, we mentioned that scientists have discovered that dogs can screen for early-stage lung cancer through their sense of smell. In the future, it may be possible to invent non-trigger screening products similar to those for early pregnancy based on research on dogs’ sense of smell.

If it can succeed, dogs will definitely make a great contribution to humans.
Dogs have already made great achievements in cancer screening, but the story I want to tell you today is even more amazing. Dogs are also very effective in cancer treatment.
Santos is a cancer patient who has been undergoing chemotherapy at the Memorial So José Hospital in Brazil since he was diagnosed.
Although Santos showed very active cooperation in fighting the disease. But after fighting cancer for a long time, the condition did not get better, but worsened. Because there was no hope, Santos began to become desperate and was not as active in cooperating with treatment as before. This vicious cycle made the situation worse.
The doctor felt that Santos' time might be running out, and informed his family to cherish Santos' last moments. The family had no choice but to be sad. In order to let Santo finish the last part of his life without any regrets, the family decided to give him a surprise: let Santo see his dog for the last time.
Santos’s dog is named Agadir. Before he got sick, they were almost inseparable, and they had a very good relationship with each other. But after falling ill and being hospitalized, they haven't seen each other for a long time.
When Santos met Agadir, Santos hugged the dog and cried like a child. He was very sad and had only one thought in his mind: Who will take care of my Agadir when I leave?
Agadir seemed to know what Santos was thinking. He rubbed his head against Santos's head as if to gently comfort his master: Master, you have to work hard to defeat the disease. I'm still waiting for you to play with me.
The heart that had been scarred and almost despairing on the road to fighting cancer suddenly felt a trace of unwillingness. Santos did not want to leave Agadir alone.
Due to physical reasons, this touching meeting did not last long, but the short time together left a very big impact. The doctor was surprised to find that Santos' condition seemed to have improved since he met the dog!
The attending doctor Rodrigo said: "Santos used to be quiet and gloomy. Now he has become cheerful, his appetite has improved, and his heart rate and blood pressure have begun to decrease."
This is not a short-term change. In the following days, Santos's health is getting better every day. The doctor excitedly told his family: At this rate, Santos might be able to be discharged from the hospital in a while!
Seeing this, some people can’t help but ask, can dogs really improve the condition of their owners?
In fact, many countries have conducted research on the relationship between pets and human health, and the medical talents of pets have long been verified.
For example, a study in the United States on the relationship between keeping pets and health proved that pets can enhance the recovery ability of their owners. The survival rate of heart disease patients who keep pets within one year after leaving the hospital is much higher than that of patients who do not keep pets!
Because pets accompanying their owners to improve their condition is not an isolated case, and it has been proven that the effect is indeed significant. Santos's hospital has already been promoting this work and began to publicize it. In the future, these four-legged little angels may enter the hospital to accompany their owners for rehabilitation.
At this moment, do you feel that it is great to have a dog?
